Answer:
C
Step-by-step explanation:
We can multiply each equation by a constant so they'll equal either 15 or -15 since that is the LCM.
Since the answer choices want us to make the top a negative 15, we'll do that.
To make the y's cancel out, the second equation would have to have the y's coefficient equal 15.
Let's do that.
So the resulting equations are answer choice C.
Answer:
We have been given the equation:
And x=10
Substitute the given x in the given equation we get:
On simplification we get:
Required solution is: x= 10 and y=-20
The solution to the system of equation is those points that satisfy the given system of equations.
